To all whom it-may concern:

Be it known that I, WILLIAM R. BROUGH, a citizen of the United States,residin at East Orange, in the county of Essex, tate of New Jersey, haveinvented certain new and useful Improvements in Electron-DischargeDevices, of which the following is a full, clear, concise, and exactdescription.

This invention "relates to electron discharge devices and especially toalcooling system therefor.

Certain types of high power electron discharge devices comprise ametallic cupshaped member which forms a portion of i the enclosingvessel and acts as the anode of the device. In the operation of thesedevices, it is customary to enclose the metallic portion with a jacket--into which a cooling fluid is introduced to remove from the anode theheat developed in it during" the operation of the device.

fluid-tight connection between the water jacket and the metallic portionof the device. An additional object of the inventlon 1s a simple andeflicient means for attachin an electron discharge device to the waterwe at.

Other objects and novel features of this invention will be apparent fromthe following specification and accompanying drawing wherein Fig. 1 is asectional view p'artially in elevation of an embodiment of theinvention, and Fig. 2 is a plan view thereof.

A water jacket is provided with inlet and outlet ports 11 and 12 and atits upper inwardly projecting screw-threaded annular flange, an electrondischarge device oom-v end has an inwardly projecting flange 13 in whichis provided a screw threaded aper- .ture.

nut. Interposed between the upper portion of the collar and the flange13 is a gasket 17.

" The device 15 with the collar 16 attached thereto is screwed into theflan e 13 and tightened against the gasket 1v until a water-tightconnection is obtained. Durin the operation of the device',. water iscaused to circulate through the jacket from the inlet 11 to the'outlet12 and serves to maintain.

the anode 14at a sufficiently low tempera- An object of this inventionis .to effect a ture to insure proper operation of'the device.

The inventionclaimed is: In combination, a water jacket having anprising ail-envelope having a metal portion, and a screw-threaded collarcarried by said metal portion to cooperate with said flange to roduce awater-tight connection between sai water. jacket and said metalp'ortionl I In witness whereof, I hereunto subscribe my namethis IOth dayof May A.
